Major codes, misfires etc..

[Amsterdamned]

What's up everyone. I just got my car back from the shop. I had a power steering return line rupture that was replaced and changed my battery under the 36 month replacement Duralast warranty. The battery only lasted 23 months. As you guys may know, the S4 has been my daily driver and has 150,000 miles. So basically a week and a half after getting my car back I had to limp home with random misfires. I got home and connected the laptop I have with VCDS. Below are the codes. I hope it's as simple as spark plugs and/or coils.

14 faults in total!

you're lucky, you don't have any timing related codes !

on the other side, check your battery voltage, with the car turned off, and while idling(make sure your alternator is charging properly) .

what exactly "triggered" this problem ? ( can you recall the last thing you did before it all started ?)

yeah, tell me about it. Pretty much nothing I can recall other than just swapping out a battery and the power steering return line.

I will check the voltage tomorrow and post back.

I hope it's not too serious. I just got her back from the shop!

Vacuum leak, my 2¢.
